据我所知,XStream 无法处理 XML 注释。
这是另一种方法,它使用 LexicalHandler API:
import org.xml.sax.*;
import org.xml.sax.ext.*;
import org.xml.sax.helpers.*;
import java.io.IOException;
public class ReadXMLFile implements LexicalHandler {
  public void startDTD(String name, String publicId, String systemId)
      throws SAXException {
  }
  public void endDTD() throws SAXException {
  }
  public void startEntity(String name) throws SAXException {
  }
  public void endEntity(String name) throws SAXException {
  }
  public void startCDATA() throws SAXException {
  }
  public void endCDATA() throws SAXException {
  }
  public void comment(char[] text, int start, int length)
      throws SAXException {
    System.out.println("Comment: " + new String(text, start, length));
  }
  public static void main(String[] args) {
    // set up the parser
    XMLReader parser;
    try {
      parser = XMLReaderFactory.createXMLReader();
    } catch (SAXException ex1) {
      try {
        parser = XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");
      } catch (SAXException ex2) {
        return;
      }
    }
    try {
      parser.setProperty("http://xml.org/sax/properties/lexical-handler",new ReadXMLFile()
      );
    } catch (SAXNotRecognizedException e) {
      System.out.println(e.getMessage());
      return;
    } catch (SAXNotSupportedException e) {
      System.out.println(e.getMessage());
      return;
    }
    try {
      parser.parse("xmlfile.xml"); // <----  Path to XML file
    } catch (SAXParseException e) { // well-formedness error
      System.out.println(e.getMessage());
    } catch (SAXException e) { 
      System.out.println(e.getMessage());
    } catch (IOException e) {
    }
  }
}
